(A) Step of Usage：
Step 1. Please confirm that your electrical supply voltage comply with charger’s input voltage
before using the battery charger.(90V~130V or 200V~240V)
Step 2. After plug in AC cord, press down key “ Battery Voltage Selection “ and select the battery
voltage you need：
a. When one LED indicator light comes on, it indicates that the charger is charging at 12 volts.
b. When two LED indicator light comes on, it indicates that the charger is charging at 24 volts.
c. When three LED indicator light comes on, it indicates that the charger is charging at 36 volts.
d. When four LED indicator light comes on, it indicates that the charger is charging at 48 volts.
Step 3. After completing step two, then the red wire connects to the positive while the black wire
connects to the negative.
Step 4. The LED display’s indicator lights will all come on with a indicator beep. Afterward the DC
battery will detect available battery power with the corresponding LED battery indicator, then the
